Apple TV is receiving a flurry of new channels today. Most prominently is a brand new YouTube app, to bring the client up-to-date with some of the other platforms. The new app reflects the design of other set-top box clients, with easier access to subscriptions and search functions. For the security conscious, the YouTube app now uses OAuth to login rather than naive password entry (by visiting youtube.com/activate)

Unfortunately, this YouTube update also means that Apple TV users will start seeing ads for the first time on the platform. Naturally, some users will be disappointed by this addition — it is not possible to opt out of the update.

Aside from YouTube, Apple TV is also getting four entirely new channels from various providers. Rolling out today are channels for Conde Nast’s ‘The Scene’, ‘Fusion’, Dailymotion (a video upload site from France) and UFC for premium subscription fighting and martial arts content.
